    摘要: Die Erfindung betrifft eine Drehräummaschine (1) mit einem Werkzeugträger (2) für Drehräumwerkzeuge (3) mit mindestens einer Aufnahmefläche zur Aufnahme von Drehräumwerkzeugen. Solche Maschinen werden zur Bearbeitung großer Werkstückserien verwendet. Die Anpassung der Lage der Drehräumwerkzeuge an entsprechend unterschiedliche Werkstückabmessungen ist umständlich und zeitraubend. Um eine solche Maschine einfacher und schneller an entsprechend veränderte Werkstückabmessungen anzupassen, wird vorgeschlagen, daß die Drehräumwerkzeuge auf der Drehräummaschine mindestens quer zur Arbeitsrichtung stufenlos verschiebbar und feststellbar sind.

    摘要: The invention relates to an internal broaching machine, comprising a machine frame, in which a machine table having at least one mount for at least one workpiece is arranged, wherein an upper pressing carriage and a lower drawing carriage are movably arranged, which each have a respective tool retainer, wherein at least one tool retainer is in the form of a vice having clamping jaws for radially clamping a broaching tool during the broaching. In the clamping state, the clamping jaws (63) of the at least one tool retainer (6) bound an internal contour (632) that narrows in the direction of the broaching tool (5) and that corresponds to the external contour of a section (52) of the shaft (51) of the broaching tool (5). The invention further relates to a method for the internal broaching of at least two workpieces (4', 4'') by means of an internal broaching machine.

    摘要: The invention relates to a tool unit (1) for producing keyways (N) or similar recesses in or on a workpiece (W), in particular for a keyway broaching machine, with at least one broach (2) moving periodically up and down in the longitudinal direction (L) of the tool and having a number of cutting edges (3), and with at least one guide rod, which extends in the longitudinal direction (L) of the tool and has a feeding wedge (5). This tool unit is characterized in that the feeding wedge (5) is arranged on the front side of the guide rod (4), facing the broach (2), and operates on a wedge-shaped feeding face (6) of the broach (2) arranged on the rear side of the broach (2), wherein the broach (2) and the guide rod (4) can be moved up and down together in the longitudinal direction (L) during a working stroke and wherein the broach (2) and the guide rod (4) can be displaced in relation to each other in the longitudinal direction (L) in the course of the feeding.
